Monitoring the VMware Cloud Director Appliance Database Cluster Health

You can monitor your VMware Cloud Director appliance cluster by using the VMware Cloud Director appliance management user interface, the appliance API, or the repmgr open-source tool suite.

You can use the VMware Cloud Director appliance management UI also to view the appliance failover mode. The failover mode indicates whether VMware Cloud Director automatically triggers a database failover if the primary database fails, or the system administrator must initiate the failover manually.

If the failover mode is inconsistent across the nodes, the failover mode is Indeterminate. The Indeterminate mode can lead to inconsistent cluster states between the nodes and nodes following an old primary cell. You must diagnose the problem and remedy the situation manually.
